3. Warnings
The DS 350 load moment indicator (LMI) with boom control extension is an operational aid
that warns the crane operator when he approaches an overload condition, a two block
condition and an out of boom sequence condition. The boom control extension controls the
sequence of the boom during operation. It still remains the operator’s responsibility to verify
the operation and to select the correct mode during crane operations.
The manual mode is a rigging mode. Lifting loads with manual mode programmed is
prohibited.
Should an out of sequence condition occur, the crane operator is responsible to select
manual mode to return the sections into sequence before continuing the lift.
The responsibility for safe crane operation shall remain with the crane operator who shall
ensure that all warnings and instructions supplied are fully understood and observed.
Prior to operating the crane, the operator must carefully and thoroughly read and understand
the information provided by the crane and load moment indicator manufacturer.
Proper functioning depends upon proper daily inspection and observance of the operating
instructions provided with the crane and load moment indicator.
